But his absence was not felt as Hanson met a Mark Yeates pass with a fierce shot into the roof of the net from 18 yards to put Bradford ahead.

Hanson, 27, lasted only 45 minutes himself before being replaced but by then had nodded City into a two-goal lead which they rarely looked like relinquishing as Phil Parkinson's in-form side climbed up to seventh.

On-loan goalkeeper Alex Cisak denied Billy Clarke and Francois Zoko as Bradford looked to add further goals after the break, while Chris Dagnall twice went close for the O's as he had a shot cleared off the line by Morais and tested City keeper Jordan Pickford.
